T 0 all whom it may concern:

Be it known that I, LEONARD SLINGLAND, a citizen of the United States,residing at Paterson, in the county of Passaic and State of New Jerse*,have invented certain new and useful Improvements in Apparatus forDeveloping Power; and I do declare the following to be a full, clear,and exact de scription of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

My invention has for its object to provide a simply constructed andinexpensive, yct'a hi lily eiiicient and durable machine for de- Veoping power from an upwardly moving current of air and with this generalobject in view, the invention resides in. certain novel features ofconstruction and unique combinations of parts to be hereinafter fullydescribed and claimed, the descriptive mat ter being supplemented by theaccompanying drawings which form a part of this speeification and inwhich Figure 1 is a vertical longitudinal section. of one form of theinvention;

Fig. 2 is a vertical section at right angles to Fig. 1, on the plane ofthe line 2-2 thereof;

Fig. 3 is a vertical section of a different form of the invention;

Fig. e is a top plan view of Fig. 3;

Fig. 5 is a horizontal section on the plane of the line 5-5 of Fi 3;

Fig. 6 is a view similar to Fig. 3 but illustrating another type of aircolumn; and

Fig. 7 is a horizontal solution on theplane of the line 7-7 of Fig; .6.I

In Figs. 1 and 2, the numeral 1 designates a vertical air column which"may be con structed in any preferred manner and of any required height,brickwork .2 being shown for supportingthe column 1, although any otherappropriate foundation could well be adopted. The lower end of thecolumn 1 is b preference flared as shown at 3 to provide for theeasyeutrance of air, whereas the upper'end of said column may either beentirely open as illustrated, or may be equipped: with a suitable damperfor con-- trolling the strength of the air current rising through thedevice. In some instances,

such a damper could well be employed at the lower end of the columnrather than at the upper end, but the use of dampers for such purposesis well known and need not be illustrated.

It is intended that a current of air shall continually rise through thecolumn 1. This column is provided at vertically spaced points with airinlets 4 which may be disposed only on opposite sides of said column, ormay be spaced around the periphery thereof at as many points as may bedesirable. Each inlet 4: is provided with a downwardly and outwardlyinclining hood 5, said hoods serving to direct any upwardly andhorizontally moving air currents on the exterior of the column 1, intosaid. column as will be clear from Fig. 1. These currents combine in thecolumn 1 to produce a single upward current of great strength which isutilized in the form of the invention under discussion, by causing it toact upon propelling members 6 which are by preference of bell-shape asshown.

The members 6 may be carried on one or more endless belt members 7, twoof said members being shown positioned adjacent opposite/sides of th' icolumn 1, said members being'connectcd by) transverse rods 8 upon whichthe propeller members 6 are carried. The rods 8 are adapted to travelupwardly in vertical slots 9.in the opposite sides of the column. 1, theupper and lower ends of said slots being curved laterally at 10 andopening through another side of the column, said last named side havingupper and lower openings 11 adjacent said curved ends of the slots,through which the propeller members 8 en tor and leave the column 1, thetwo belt members 7 being so arranged that said members will travelupwardly in the column, but will move downwardly on the exteriorthereof.

The upper and lower portions of the belt members 7 are trained aroundwheels 12 which will be in the form of sprockets if said belt members besprocket chains as illustrated, said wheels being secured on upper andlower shafts 13 which are spaced outwardly from the column 1. Suitablebearing arms 14- rotatably support the shafts frames 15 which surroundand are secured to the column 1, it being the principal ofiice of theseframes to prevent spreading or narrowing of the slots .9. Any suitablemeans may be provided for driving numerous types of machines from theapparatus, but for illustrative purposes I have shown a pulley 16 on thelower shaft 13.

' The arrangement of parts shown and described will be highly efficientand it will be obvious that any drafts of air, whether movinghorizontally or upwardly, will be caught by the hoods 5 and the flare 3,so that they are directed upwardly through the column 1 to elevatethe-propeller members 6 therein, so that the shafts 13 are driven toderive power. it is also to be understood that currents of air risingfrom any cause, such as heat, will operate the device by passingupwardly through the column 1, it being worthyof note that the shape ofthe propeller members 6 will cause little resistance as these membersmove downwardly, but will exert a powerful pull upon the belt members 7as the current of air in the column 1 strikes them.

In Figs. 3, l and 5 a vertical column 1 is shown having air inlets 4:equipped with hoods 5', a suitable superstructure 2' being employed forsupporting said column. In this type of the invention, the lower end ofthe column l need not be flared and the upper end thereof will bypreference be equipped with a pair of horizontally sliding dampers l7suitably mounted on a sup port 18 carried by the column, cables or thelike 19 being employed. in order that said dampers may be actuated fromthe lower end of the column to increase or decrease the strength of theair current passing upwardly therethrough.

In the form of the device now being described, the endless belt membersand the propeller members above described are dispensed with and in lieuthereof, a vertical shaft 20 is positioned coaxially in the air column1', said shaft having propelling members 6 in the form of fan blades, sothat the upwardly moving current of air through the column 1 will actagainst these blades to rotate the shaft 20. Any preferred type ofbearings 21. and22 may be employed at the upper and lower ends of theshaft 20, respectively, and a pulley or the like 16 will in most casesbe utilized for taking power from said shaft to drive numerous kinds ofmachinery.

In Figs. 6 and/i, the construction is pres tically identical with thatillustrated in Figs. 3, 4 and 5, with the exception that the nee-instair column 1 decreases gradually in diameter toward its upper end but isflared at the latter as shown. at 3. When this construction isemployed,'the propellers 6" on the shaft 20 will decrease in size towardthe upper end of the device and in numerous instances this arrangementwill be found of advantage.

Figs. 6 and 7 illustrate hoods 5 over the vertically spaced air inlets4, the function of these parts being identical with the shin larfeatures above described. A pan-like member 18" is also shown, saidmember being carried by the upper end of the column 1 and serving asimilar function to the part 18 above described.

From the foregoing, taken in connection with the accompanying drawings,it will be obvious that although the several types of my invention areextremely simple and inexpensive, they will be highly efficient anddurable for developing power from an upwardly moving current of air, andthat this Eli power may be utilized in countless ways, it.
